Begin by preheating your oven to 375°F (190°C). This ensures a hot environment for the chicken to bake evenly.
Take each chicken breast and carefully slice a pocket into the thickest part. Make sure not to cut all the way through; you want to create a pouch for the filling.
Season both the inside and outside of each chicken breast generously with salt, freshly ground black pepper, garlic powder, and Italian seasoning blend to enhance flavor.
Inside each pocket, spread approximately 2 tablespoons of fresh basil pesto. Then, insert 2 slices of fresh mozzarella cheese, ensuring even distribution.
To keep the filling secure, use toothpicks to close the openings of the chicken breasts carefully.
In a large, oven-safe skillet, heat the 2 tablespoons of extra virgin olive oil over medium-high heat until shimmering. Add the stuffed chicken breasts to the skillet and sear each side for about 4-5 minutes until they are golden brown and crispy.
After searing, transfer the entire skillet to the preheated oven. Bake for 20-25 minutes, or until the chicken is cooked through, reaching an internal temperature of 165°F (75°C).
In the last 10 minutes of baking, scatter the halved cherry tomatoes around the chicken in the skillet. This will allow them to roast, enhancing their sweetness and adding flavor to the dish.
Once baking is complete, remove the skillet from the oven and allow the chicken to rest for about 5 minutes. Gently remove the toothpicks that secured the pockets.
Serve the succulent stuffed chicken with a drizzle of extra pesto on top if desired, and garnish with fresh basil leaves for a vibrant touch.
